Anhinga birds and Double-crested Cormorants are very similar aquatic birds. The differences are the bill and body size with only faint differences about the feathers. The Anhingas are more slender and have a very straight slender sword-like bill. The female Anhinga is more brown in color with a light tan throat. These females are also nicknamed “Piano birds” for the pattern of their feathers.
The Double-crested Cormorants can be distinguished by the slightly hooked tip of their long also sword-like bill. The cormorants also are much heftier and blocky in body than the Anhingas. Both eat fish, frogs, and small turtles. Both are experts in flight as well as swimming. Both the Anhingas and Double-crested Cormorants are referred to as “Snake birds” as they come up from diving with only their long sinuous neck and their head peeking out of the water.
The Anhingas are here all year long but the cormorants mostly are migratory with the White Pelicans. Please click on the thumbnail image to see the slightly larger version of the picture. Enjoy!
